To see webpack warnings, you can utilize the terminal or command prompt while running your webpack build. By default, webpack outputs warnings in the terminal along with any error messages.


To view warnings, follow these steps:

  1. Open your terminal or command prompt.
  2. Navigate to the root folder of your project.
  3. Run the webpack build command: $ webpack or if you have configured specific scripts in your package.json file: $ yarn build or $ npm run build


While webpack is compiling your code, it will display any warnings it encounters in the terminal. These warnings typically include messages about unused variables, potentially dangerous code constructs, or other issues that might cause problems but won't stop the build process.


You can also customize webpack's configuration to change the verbosity of the warnings. By altering the stats object in your webpack configuration file (usually webpack.config.js), you can specify the level of detail for warnings.


Here's an example of configuring webpack to display minimal warnings:

1
2
3
4
5
6
7
module.exports = {
  // ... other webpack configuration options

  stats: {
    warnings: "minimal",
  },
};


With this configuration, webpack will only output the minimal level of warnings. You can adjust the value of warnings to "verbose" or "none" based on your requirements.


Remember to rebuild your code after making changes to the webpack configuration.
